Abstract

The Opak Samiler business group in Wonosunyo Village uses manual production methods, resulting in low productivity only 3 kg of dry opak per day, produced only in their free time after fieldwork. The lengthy and skill-intensive dough flattening process, along with uneven opak thickness, frequently receives consumer complaints. High demand, particularly during Eid al-Fitr, is difficult to meet due to limited production capacity and weather conditions. Therefore, this community service project aimed to increase the business group's productivity by implementing Lean Tools-based work aids: a mechanical samiler printer and a drying machine. The implementation involved socializing and training the business group members on tool use, and evaluating the production process post-implementation. Consequently, these work aids increased productivity by up to 65% compared to conventional methods.

Abstract

General Background: Quality control in textile manufacturing is essential to maintain production consistency and minimize nonconforming products that can disrupt operational performance. Specific Background: PT EQY, a yarn spinning manufacturer, recorded 1,475 bales of nonconforming products from a total production of 39,719 bales during August 2023–July 2024, exceeding the company’s tolerance threshold and indicating quality deviations within the production process. Knowledge Gap: Prior quality monitoring within the company lacked integrated analytical methods that systematically combined statistical monitoring tools with continuous improvement strategies to comprehensively identify defect patterns and corrective actions. Aims: This study aims to identify dominant defect types in yarn production, evaluate process stability using Statistical Process Control tools, and formulate corrective strategies based on Kaizen principles. Results: The analysis identified three dominant defect categories, including swallot defects totaling 560 bales, products without tail totaling 473 bales, and color inconsistency totaling 442 bales. Control chart analysis indicated several production periods exceeding statistical control limits, reflecting unstable production processes. Root cause analysis using fishbone diagrams identified machine maintenance scheduling, production methods, workforce discipline and training, and environmental conditions as primary contributing factors. Novelty: This research integrates Statistical Process Control with Kaizen-based analytical frameworks, including 5W-1H analysis, Five M checklist, and 5S implementation, within yarn production quality monitoring. Implications: The proposed analytical framework provides structured guidance for identifying production deviations, supporting systematic waste reduction and continuous quality monitoring in textile manufacturing operations. Highlights: Swallot Category Recorded the Highest Nonconforming Quantity During the Observation Period. Statistical Monitoring Identified Several Production Months Exceeding Control Boundaries. Root Cause Mapping Identified Maintenance Routines, Operator Training, Procedural Practices, and Workplace Conditions as Primary Contributors. Keywords: Statistical Process Control, Kaizen, Yarn Production, Quality Monitoring, Production Defects

Abstract

This research evaluates the efficiency of the MGTR-RF15 machine at RMP that focuses on raffia packing. In the last 6 months, MGTR-RF15 has experienced 100 times downtime which has caused the production process to stop temporarily, hampering the fulfillment of customer requests and increasing logistics costs. This study aims to determine the level of machine efficiency, determine the cause of the highest risk, and provide alternative suggestions for improvement. This research uses the Overall Equipment Effectiveness (OEE) and Failure Mode and Effect Analysis (FMEA) approaches. MGTR-1F15 OEE value of 82.91% is below international standards with availability as the dominant factor affecting efficiency. The FMEA identified the bent strap clamp iron as the critical failure with the highest risk worth RPN 280. Root Cause Analysis (RCA) shows the root cause of the downtime problem so that alternative recommended improvements include routine training, implementation SOPs, inspection raw materials, and selecting high-quality suppliers.

Abstract

Weaving machines play a crucial role in ensuring the smooth running of the textile production process. Repeated machine failures can lead to decreased production output and increased downtime. This study aims to identify potential failures, analyze the root causes of weaving machine failures, and prioritize appropriate repairs. The methods used are Failure Mode and Effect Analysis (FMEA) and Fault Tree Analysis (FTA) to identify failure modes and root causes of damage, as well as the Age Replacement method through the calculation of Mean Time Between Failure (MTBF) and Mean Time To Failure (MTTF) to analyze the level of machine reliability. Data were obtained from observations, interviews, and historical data of machine failures. The findings indicate that the shuttle, oil pump, and connecting rod are the most critical components of the weaving machine, as they recorded the highest Risk Priority Number (RPN) values of 360, 280, and 245, respectively. These results suggest that the three components should be given priority in maintenance planning. The analysis further revealed that their failures are primarily associated with component wear, excessive friction, poor lubricant quality, blockage within the lubrication system, excessive operating loads, high vibration levels, and improper component installation. Based on the Age Replacement analysis, the recommended preventive maintenance interval is 243 operating hours for repairable components and 87.4 operating hours for non-repairable components. Implementing these maintenance intervals is expected to reduce the frequency of machine failures, minimize downtime, and improve the overall reliability and operational performance of the weaving machine.
